WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 671,339, dated April 2, 1901.

Application filed January 26, 1901. Serial No. 44,891. (N mode -J I0 aZZ whom it may concern:

Be it known that NORMAN N. HAZELTON,

deceased, late a citizen of the United States,

who resided at Lamoni, in the county of De- 5 catur and State of Iowa, invented certain new and useful Improvements in Weather-Strips,

of which the following is a specification.

.The invention is an improvement in weather-strips applied to or embodied in the to threshold of a door, and has for its objects,

among others, to provide means whereby the ingress of snow and water may be prevented, by which the door may readily operate the weather-strip proper into and out of position I 5 to shut off the ingress of snow and water, and

by which the operation of such weather-strip proper may be facilitated.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of the invention as in use, a portion of the door being broken away and the door being shown partially open. Fig. 2 is a detail cross-section drawn alongside the swinging edge of the door, the door being closed and the other parts being in the position assumed when the door is closed. Figs. 3 and 4 are cross-sections of the threshold and weather- 0 strip proper, showing the latter in Fig. 3 in 5 edge of the door, showing the weather-strip proper with its guard-plate slightly elevated and illustrating how the door, if moved in the direction indicated by the arrow, will adjust the weather-strip proper to the position shown in Fig. 4 before the arm of such part is engaged by the operating part on the door, and Fig. 6 is a detail perspective View of the weather-strip proper.

The threshold A is provided in its upper face, near its outer edge, with a longitudinal recess B, in which is seated the weather-strip proper, C, so the latter can turn or partially rotate. To facilitate this, it is preferred to curve the base of the recess B circularly, as

shown, and provide it with a plurality of balls or similar antifriction devices D,which project into the recess and receive the bearing of the weather-strip O. The rear wall B of the recess 'B is prolonged upwardly and rearwardly to the upper face of the threshold, and a retaining-plate E is secured upon the threshold and projects at its forward edge over the recess B and contracts the mouth thereof, as will be understood from Figs. 3 and 4. It will also be noticed from Figs. 3 and L that the upper face of the threshold in advance of the recess Bis arranged in a lower plane than the upper face of such threshold in rear of such recess, which construction permits the insertion and removal of the weather-strip proper in certain adjustments thereof, as will be more fully described.

The weather-strip proper is shown as constructed with the guard-plate G and below the same with a curved segmental rib G and above the same witha curved segmental rib 0 which is curved on a smaller arc than the rib O coincides at its rear edge with that of the rib O and terminates at its front edge in rear of the corresponding edge of the rib C as is clearly shown in Figs. 3 and 4. By this construction it will be seen from Fig. 4 that when the weather-strip proper is adjusted with its guard-plate fiat upon the depressed front face of the threshold, as shown in said Fig. 4, the overlapping plate E will prevent the withdrawal of the part 0 from its recess, also that such withdrawal cannot be accomplished until the part 0 has been adjusted to the position shown in Fig. 3, when it can be lifted in the direction indicated by dotted lines, which illustrates how the weather-strip proper can be inserted into and removed from the threshold. It will also be noticed that the position of .the weather strip proper (shown in Fig. 3) is only assumed by such part in the operation of the device when the door is closed, as shown in Fig. 2, so there is no danger of the accidentaldisplacement of the weather-strip proper, since it is only adjusted to the position shown in Fig. 3 by the closing of the door, which when closed will lock the part 0 in place, or intentionally when it is desired to insert or withdraw the part 0.

At one end of the weather-strip O is provided an arm 0 formed on its edge 0 for engagement by the operating-piate F at the swinging edge of the door, and the rib O iscut away at adjacent to the arm 0, to permit the operation of the wedge-plate G, which is also-secured to the door at the swinging edge thereof.

The door His provided atthe lower end of its swinging edge with a notch H, in which wardly toward the inner face of the doorfrom.

its upper to its lower edge, so thatin opening the door the tongue F will operate with a J wiping action upon the guard-plate C to adjust the part 0 from the position shown in Fig. 2 to that shown in Figs. 1 and 4. The

plate G is secured in the notch H near the inner face of the door and has its lower edge G curved or inclined, so'it will operate-witha wedgi ng action upon the plate 0 and force such plate down to the positionshown in Fig. 4 in case it shouldaccidentally have been moved into the position shown in Fig. 5 when the door was open. edge G will ride upon the plate 0 and throw the strip 0 to the position shown in Fig. 4 before the tongue F operates upon the arm 0 to move the weather-strip to the position shown in Fig. 2.

Where desired or necessary, the weatherstrip may be provided with suitable vents I to drain off any water that may get into the recess for the weather-strip proper.

From the foregoing itis obvious the'weatherstrip will operate when the door is opened as a wear-plate for the sill, will not interfere in any way with the use of the sill, will be adjusted by the door to position to serve-as a weather-strip when the door is closed, can only be inserted or removed when tilted to one position, and will not assume such position inthe use of the device except-when the door is closed, at which time the door will prevent the withdrawal of the weather-strip proper, so that the latter can only be inserted or removed when intentionally adjusted to a certain position when the door is opened.,

The construction is simple, easily applied, and the provision of the antifriction-bearings D renders the operation of the weather-strip proper smooth and easy.

Having thus fully described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. A weather strip substantially as described, comprising a threshold having alongitudinal recess in its upper face, havingsuch face in advance of the recess formed in a-lower plane than the'corresponding face in rear of the recess, the retaining-plate secured upon the threshold in rear of the-recess and projecting at its front edge over the recess, and the weather-strip proper formed with the guard-plate, and with the curved ribs above and below the plane-of such plate, theupper rib being curved on a smaller arc than the lower one and such ribscoinciding approximately at the rear edge of the weather-strip, all substantially as and for the purposes set forth.

2. The combination of the threshold provided with a recess forming a journal or seat for the weather-strip proper and having antifriction devices in the base of said seat, and

l the weather-strip proper having a guard-plate and a portion fitting and journaled in the recess of the threshold and provided with means whereby it may be automatically operated by the opening and closing of the door, and the door arranged to operate the weather-strip,
